CORI-FLOW™ Coriolis Mass Flow Meters and Controllers are designed to deliver high accuracy even under varying operating conditions. Using advanced Coriolis technology, mass flow is measured directly, eliminating the influence of fluid density, temperature, conductivity and viscosity. The instruments are ideal for applications that require both accuracy and flexibility, with the ability to connect control valves for smooth flow regulation.
The check valves are modularly designed, allowing the user to change or upgrade them without adjustments. The standard valve is normally closed and can handle Kv values up to 1.5, but normally open valves can also be supplied.
Features and benefits:
- High accuracy: Measures mass flow independent of fluid properties.
- Modular valves: Easy replacement or upgrade of control valves without adjustments.
- Flexible flow range: From 0...5 kg/h up to 0...600 kg/h.
- Rapid response: For dynamic and precise process control.
- Robust construction: Withstands pressures up to 200 bar for demanding industrial environments.
Applications:
- Chemical industry: Accurate dosing and mixing of chemicals.
- Food industry: Flow measurement and control for ingredient handling.
- Pharmaceutical industry: Precision control of liquids for pharmaceutical production.
- Oil and gas: Measuring flows under high pressure and extreme conditions.
